Sorry for the long post, but I have a question I need some help with.

I was cleaning out the garage and found an old fishfinder (Eagle Fish I.D. 128)I had taken off my boat a few years back. The transducer is busted but I found a replacement on the internet for about $50. So that got me thinkin, how can I mount this transducer off the front of my pontoon boat where I fish at? I don't want to mount it on the back because thats over 20 ft away from where I am fishing. I thought about just mounting it to a 3ft piece of 1x4 and just clamp the top of the board to the front railing after I get to my fishing hole. P.S. I don't have a trolling motor to mount it to.

Any other ideas on how to mount this transducer up front?

Thanks!! -Toad
